    Areas affected...north Texas

    Concerning...Severe Thunderstorm Watch 548...

    Valid 110148Z - 110445Z

    The severe weather threat for Severe Thunderstorm Watch 548
    continues.

    SUMMARY...The severe hail and wind threat is expected to continue east/southeast across the watch area.

    DISCUSSION...A cluster of strong to severe storms, previously over
    the Wichita Falls area, is expected to persist east/southeastward
    across north TX, and possibly merge with other activity north of
    Denton. Despite loss of heating, cold air aloft with the upper
    trough will overspread the moist sector where low 60s F dewpoints
    remain, which will maintain favorable instability. Further, the
    organized nature of the western cluster suggests several more hours
    of wind and hail potential extending east/southeastward across north
    TX. In addition, 0-1 km SRH of 200-300 m2/s2 may yet support a brief
    tornado with cells preceding the main outflow surge.
